Beware Who You Trust, Satan Was Once an Angel (слэш)

“Food, sleep, exercise, sunlight,” Peter counts the words out on his fingers. “As pedestrian as that advice is, it does work.”
“Is that what you did after you came back from the dead?”
Peter smirks and straightens his back in a way that makes the muscles of his chest and arms stand out.
“We’re going for a run,” Peter ignores Stiles’ sarcasm-laden question, “thirty minutes. For those thirty minutes, you don’t have to put on your normal Stiles mask and you can ask me any question you can come up with.”

Peter Hale notices that Stiles isn’t quite dealing with the aftermath of his possession, so he decides to help.
Only to ensure his own survival, of course.
